First Traces
Meet the logic of shapes and patterns.

Beyond
numbers.
Three shapes and three patterns form nine distinct objects. In a cell, hide only the shape or only the pattern; as long as the visible clues still point to what you hid, the logic holds.

The first 5 Discovery levels are free; the other 29 unlock permanently with a one-time pack. The iOS version is in App Store review.
Discovery I · Layers
Every removal,
a new discovery.
Each row, column and outlined nine-cell region contains every shape–pattern combination exactly once.
A move is valid when all objects compatible with the remaining visible clues share the same value for the hidden feature. A single complete object is not required.
Crossing Paths
Choose your removal order among crossing clues.
Hidden Links
Read how partly visible objects constrain one another.
Deep Layers
Keep the proof intact as fewer clues guide you to the core.
Classic mode
A number goes.
Its reason remains.
Treat a cell as empty. If the numbers in its row, column and region rule out all eight other digits, you can remove its number. Exactly one candidate must remain to recover it.
If you need to fill other empty cells first, this move is not valid yet. The number you remove first changes your next choice.
Beside this is a small web demo with classic 3×3 regions. The mobile game’s Mosaic levels, daily board and save system are not included.

Inside the game
The removal order,
the trace of the solution.
The proof strip shows why a move is valid. The solution trace restores removed numbers in reverse order, letting you follow your own decisions step by step.
A daily board and a freeform workshop, three themes and ten languages. Your last game and personal records are saved on your device.
The images were prepared from the current Flutter interface. On the right are Mosaic level selection and details of a move’s reasoning.
